DOUBLE-SEAMING STAKE.

Application filed June 10, 1919.

[0 all whom it may concern Be it known that I, JononN OLSON, a citizenof Norway, residing at Cashton, in the county of Monroe and State oflvisconsin, have invented certain new and useful Improvements inDouble-seaming Stakes, of which the following is a specification.

This invention relates to metal bending, and more especially to thecombined operation of bending and curving; and the ob ject of the sameis to produce a tinners stake by means of which a round article can bedouble seamed with the proper tool.

A further object is to shape the seaming head so that it will enter therather small mouth of a untensil having a breast, such as a tea kettle,but the active face of this head is shaped so as to facilitate doubleseam ing when the work is in place thereon.

Another object is to provide the tool with a detachable and adjustablesupport sothat a cylindrical piece of work can be mounted thereon.

Details are set forth in the following specification and claims, andreference 1s made herewith to the drawings, wherein:

Figure 1 is a perspective view showing this device as employed forsupporting a cylindrical piece of work such as a can.

Fig. 2 is an elevation showing this device employed in the act of doubleseaming a tea kettle.

Fig. 3 is a detail of an extra seaming head having a working face oflarger curvature.

Cylindrical work is typified herein by the can C shown in Fig. 1, whilework with a contracted mouth is typified by the tea kettle T shown inFig. 2. In both these pieces of work the bottom is applied by a seam S,and D designates the same seam after it has been given its second bendso as to produce a double seam. The present invention is a tinners stakewith attachments, whereby a tinner having the ordinary tools can doubleseam work of either class. Coming now to the details of the presentinvention, the numeral 1 in the drawings designates a work bench havinga socket 2 into which is inserted the spur 3 at the inner end of an arm4 which is possibly three feet long and projects out horizontally beyondthe bench as shown. Carried by its outer end is an upstanding seaminghead 5 whose lower end may have a pin 6 seated in a socket 7 in the arm,but whose upper end is widened and Specification of Letters Patent.

arched, the face 8 being also beveled inward as best seen in Fig. 2, andthe arch or curvature being such as is useful on the smallest size ofwork to be treated. It is thus pos sible to have this head removablefrom the arm so that one of larger curvature, as seen in Fig. 3, can besubstituted, but a simpler arrangement would be to have two completetools whereof one has a rather small head and the other a rather largehead, then either could be used according to the requirements of thecase, and the head in each tool would be fastened to the arm.

The numeral 15 designates the head of a support, also preferably havinga comparatively narrow body and a widened upper end, but the active face16 of this head, while curved on substantially the same are as the faceof the seaming head, is fiat transversely rather than being inclined orbeveled. The lower end of the support is forked as shown at 14, and thefork arms pass astride the main arm a, a set screw 13 being passedthrough one of said fork arms for purposes of adjustment.

A screw bolt 12 is extended through the head 15 directly above theforked arms of the same and is adapted for strengthening the arms andpreventing the same from cracking under the strain of the screw 13.

In the use of this device on a can or other plain cylindrical work asindicated at C in Fig. 1, the support is applied to the arm and properlyadjusted, and then the can is slipped over the seaming head and thesupport, and the seam formed first as at S and then as at D. In the useof this tool in connection with a kettle T having a contracted mouth asindicated in Fig. 2. the mouth is inserted over the seaming head whosepeculiar shape pen mits it to enter a comparatively small mouth. andthen the work is passed over the arm 4 until the bottom of the teakettle T or other object lies against the end of the arm and the outerside of the head 5. The work is then borne down onto the active face 8,and the bottom is first seamed onto the body thereof, as indicated at S,and then double seamed as indicated at D. It may not be necessary to usethe support in this case. Or, it is quite possible to provide the outfitwith a plurality of supports of different sizes, and use that which fitsmost accurately to the work being handled. Still, the provision of thefork 14 and set screw 13 in Cir lwul

the support shown, renders it adjustable and, therefore, useful on workof a variety of sizes.

Having thus described the invention, what is claimed as new is:

1. A device of the class described including an arm having attachingmeans, a seaming head carried by the arm and having its outer portionarched, the'outer face of said seaming head being beveled inwardly, anda second head carried by said arm in spaced relation to said first namedhead, said second named head being adjustable on said arm and having itsouter face disposed in the horizontal plane of the outer face of saidfirst named head.

2. A device of the class described includ ing a horizontal supportingarm, a seaming head extending from the outer end portion of said arm,the lower end of said head being relatively narrow and the upper endbeing widened and extended transversely of the said arm and having acurved active face beveled toward the inner. end of the arm, and asupport adjustably connected at its lower end to said arm and having itsupper end widened and extended beyond the sides of said arm, saidsupport being ar' ranged in spaced parallel relation to said seaminghead.

In testimony whereof I affix my signature.
